MACH
Description
Genome-wide association studies (GWAS) can identify common alleles that contribute to complex disease susceptibility. The effects of most common SNPs must be evaluated indirectly using either genotyped markers or haplotypes thereof as proxies. MACH software implements a computationally efficient Markov Chain framework for genotype imputation and haplotyping. The approach describes sampled chromosomes as mosaics of each other and uses available genotype and shotgun sequence data to estimate unobserved genotypes and haplotypes, together with useful measures of the quality of these estimates.
